Bought the Pirates of the Carribean 4 from iTunes a while back and finally got around to watching it yesterday. Well I noticed that it was putting a subtitle up for any signs that came into the screen. Like at the beginning when it showed the title of the movie it also put the title in white plain letters at the bottom of the screen. One other instance was when the Queen Anne's Revenge ship passed by and the name on the back of the ship came into view it again put the name at the bottom of the screen in plain white letters. What is this and how do I turn it off? Is it subtitles? This is the first movie i have ever seen this on.
